Tropical Rainforest
BY BLAKE, JACK, RICKY AND BELLA
Geography (Blake)
I will teach you where this biome is found, a map that
clearly identifies where this biome is, a description
of the physical landscape and a explanation of how
humans use the Tropical Rainforest.
Where is this Biome found?
Tropical rainforest are usually located near the
equator. Fifty seven percent of all tropical rainforest
are found in Latin America. One third of the world’s
tropical rainforest are in Brazil.
Here is a map of where
this biome is found.
Physical Landscape
The tropical rainforest has dense and lots of thick
trees. The tropical rainforest has most of the biggest
trees in the open. They can go from 100-200 ft tall,
they are exposed to dry winds. And they have a
unusual root system compared to trees in the cities.
Human uses
Humans use the tropical rain forest for many things,
one thing that they use it for is for medicines. Did
you know that 25% of all the medicines in the world
come from the plants in the Rainforest. Also the
tropical rainforest are home to many tribal groups,
they are not named, but there are about 600 people
that live in the rainforest.
Meteorologist (Ricky)
Hi, I’m going to teach you about the climate and
environment about Tropical Rainforests.
Weather and Climate
Tropical Rainforests are very humid, receiving 250cm
of rain each year. Tropical Rainforests are very wet
because of the hot and cold weather near the
rainforests. These rainforests are mostly found on or
near the equator. The water on or near the rainforest
evaporate so very quickly because of the heat of the
sun. Because of the elevation the clouds can’t hold
that much water vapor.
Temperature
The average temperature of these rainforests, is about
77 degrees fahrenheight. Water can not freeze in
these temperatures. The reason Tropical Rainforests
are so hot is because there is so much radiation on
the equator. Temperatures have never gotten below
64 degrees fahrenheight.
Environment
You would die in 2 hours in a Tropical Rainforest
without shelter because of the heat. You would still
die even if the weather was humid. Certain animals
have many sweat glands so they can withstand the
heat.
Zoologist (Jack Cu)
I will teach you about the a biotic an Biotic factors to
help these types of animals. I will identify three
herbivores, carnivores, omnivores and rain forest
food chains also decomposers. I also will teach you
about adaption's
Herbivores
 Howler monkey, howlers live high up in the forest
canopy they eat fruits and nuts.
 Capybara, the worlds largest rodents lives on the
forest floor and spends a lot of time in the water.
 They eat leaves and fruits and also plants from the
bottom of rivers and lakes.
 Tapir, found on the floor also spend some time in
ponds Amazonian tapirs are considered browsing
herbivores feeding on herbaceous vegetation fruits
they really like bananas and even aquatic plants.
Carnivores
 Green anaconda, at the top of the food chain and one
of the larges snakes in the world. lives on the banks
of the Amazon river and spends time in the water
they eat large rodents small mammals, frogs and
fish.
jaguar, the largest and most powerful member of the
Amazon cats top of the food chain and among the
largest living cats in the world
Harpy hawk, lives in the emergent layer.
Eats mostly small birds. This eagle eats anything and
only a few animals are not threatened.
Omnivores
 Toucan, toucans live in the forest canopy. Eats
tropical fruits spiders lizards frogs snakes and even
plunder nests.
 Poison dart frogs lives in the leaves and plants on the
floor of the rain forest near streams and rivers.
 White faced monkey, they quietly roam around the
middle canopy in small groups looking for food.
Rain forest food chain picture
Rain forest food chains
 As there is a plentiful and constant supply of food
from the producers. This means that there are more
primary consumers (an animal that that depends on
plants e.g. caterpillar or katydid) here than any other
ecosystem. This then means that there are more
carnivores (secondary consumers) and thousands of
decomposers to recycle the dead material. This
means the rainforest the most complicated food web
on earth. In order to survive then the insects have
developed many defenses such as camouflage and
poisons.
Decomposers
 Termites
 Termites make nest in the rain forest trees.
 They eat wood.
 They are eaten by frogs, birds, and giant anteaters
Termites have a important job to eat dead trees
Adaption's
Some of the most beautiful and unique animals of
the world are found in rainforests of the world.
Flying frogs, rabbit sized bird-eating spiders,
jumping athletes chimpanzees, large gorillas,
dangerous cobras, etc. are some examples of strange
animals found in rainforests. Toucans, jaguars,
tarantulas and bears are common in rainforests. Life
of all animals inside the wet and dense rainforests is
full of struggle and danger. Only the smarter and
stronger animals who successfully adapt to the
environmental conditions, survive .
Biotic and a biotic
 Biotic factors are living things in an environment.
Tropical rain forest is full of life with approximately
15 million different species of animals. A few
examples of the many biotic features are the rubber
and bamboo tree, sloths anteaters, posing dart frogs
 Lemurs, bromeliads, etc.
 A biotic factors of the rainforest include soil, water,
rocks, light and climate.

Botanist (Bella)
I will teach you about some of the plants in a tropical
rainforest and how they adapted to life there.
Plant Factors
Soil: The soil here is very poor and infertile so plants and
tree’ s roots aren’t deep down. This is way some trees in
the rainforest form buttresses and some plants grow prop
and stilt roots.
Climate: The climate here is warm and humid. This makes
the plants decompose making new, fresh soil on top of
the old for more plants to grow on. Also it is warm here
all year round.
Sun: The sun is bad here because all of the sun is being
taken up. What I mean is that all the plants race up high
to get the sun, that’s why rainforest have tall trees, etc.
This means all the plants below don’t get as much sun
resulting in them decomposing.
Plants
Madagascar Rosy Periwinkle:
 It has white petals, a pink center, and glossy, green
foliage
 It can be used as a drug to cure childhood leukemia
and cases of Hodgkin's disease
Orchids:
 Common in tropical regions
 They grow on other plants
 Colorful flowers that come in white, pink, purple, etc.
Plants continued…
Raffles’ Pitcher Plant:
 A pitcher plant
 It is carnivorous
 Found in Southeast Asia
 Can grow up to 30 ft. tall with the pitcher at 12 in. tall
 It is full of insects and sometimes small mammals and reptiles
try to steal the insects but the plant gets them
Bromeliads:
 Related to the pineapple family
 Has thick, waxy leaves
 Catches rainwater
 Provides homes to frogs and their tadpoles, salamanders,
snails, beetles, mosquito larvae, etc.
 It is like a mini ecosystem
Plants continued…
Lianas:
 Woody climbing vines that drape rainforests
 Adapted by having roots in the ground and climbing up
to reach the sunlight
 Sometimes starts in trees and goes down
Maidenhair Fern:
 Grows in the shaded parts of the rainforest
 Withstands hot summers by curling its fronds
 Very delicate
 Grows from 1 to 2 ft. in height
 Used to create herbal medicines
Plants continued…
Elephant ears:
 Ground plant
 Massive leaved
Mango tree:
 Green leaves
 Grows mangoes
 Mangoes turn reddish orange when ripe
 Animals such as monkeys eat the mangoes on the
trees
Plants continued…
Bird of Paradise:
 lives mostly in South Africa
 Has orange and blue petals
 Thrives in humid climates like the rainforest
Red Passion Vine flower:
 Attracts birds and insects to it from its bright color
 Looks like it has 10 petals but it has only 5
Adaptations
Bark:
The trees have thin, smooth bark helping to adapt to other
plants trying to grow on it. It makes it harder for plants
to grow on the trunk so that they can reach the sunlight.
Drip Tips:
Leaves in the rainforest have drip tips helping to get the
rain off the plant, considering this biome gets lots of
rainfall. Plants also need there drip tips because if the
rain stays on the plant bacteria and fungus can grow in
the water on the plant, infecting the plant.
Adaptations continued…
Buttresses:
These are massive ridges that form at the bottom of
trees. They can grow up to 30 ft. tall before blending
in the tree. Trees have these because the soil is
unfertile and poor making the not being able to have
deep roots. Buttresses provide support to the tree.
Prop and Stilt Roots:
These roots provide support to tropical palms in wet,
shallow soils. These roots grow above ground but
these roots grow very slowly sometimes only getting
to 28 in. high in 1 month.
Adaptations continued…
Epiphytes :
These plants have adapted by growing on other plants
like tree trunks and branches. They do this so that
they can reach the sunlight at the top of the
rainforest. Other tiny plants that live on the leaves of
an epiphyte are called epiphylls.
